Definitions
- Venturis extend from the cavity 18, they are spaced apart and, after passing through virtually the entire cup-shaped support 3, open into an arcuate channel 26 which extends as two branches, themselves extending upperly into two vertical channels 28 which pass through the sheet metal 6 of the hob and are each provided with a rim 30 projecting upwards to an extent equal to the rim 22 of the cavity 18.
- a vertical venturi conduit 50 is provided in the inner cylindrical portion 40 of the burner 38 and upperly faces the nozzle 16 of vertical axis. It opens upperly into a circular chamber 52, the outer wall of which comprises a plurality of ports 54.
- the annular chamber 47 is closed upperly by a removable annular cover 56, while the circular chamber 52 is closed upperly by a circular cover 58.
- the gas flow leaving the two nozzles 14 entrains into the cavity 18 another flow of primary air originating from the top of the hob 6 via a first passage defined lowerly by this latter and upperly by the outer edge of the burner 38, and then via a second passage defined lowerly by the depressed rim 20 of the cavity 18 and upperly by the burner 38.
- the burner operates with the flame rings fed simultaneously, as in the case of traditional burners.
